According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The iscsi_if_rx function in     drivers/scsi/scsi_transport_iscsi.c in the Linux kernel     through 4.13.2 allows local users to cause a denial of     service (panic) by leveraging incorrect length     validation.(CVE-2017-14489)

  - The move_pages system call in mm/migrate.c in the Linux     kernel before 4.12.9 doesn't check the effective uid of     the target process, enabling a local attacker to learn     the memory layout of a setuid executable despite     ASLR.(CVE-2017-14140)

  - The offset2lib patch as used in the Linux Kernel     contains a vulnerability that allows a PIE binary to be     execve()'ed with 1GB of arguments or environmental     strings then the stack occupies the address 0x80000000     and the PIE binary is mapped above 0x40000000     nullifying the protection of the offset2lib patch. This     affects Linux Kernel version 4.11.5 and earlier. This     is a different issue than CVE-2017-1000371. This issue     appears to be limited to i386 based     systems.(CVE-2017-1000370)

  - Race condition in fs/timerfd.c in the Linux kernel     before 4.10.15 allows local users to gain privileges or     cause a denial of service (list corruption or     use-after-free) via simultaneous file-descriptor     operations that leverage improper might_cancel     queueing.(CVE-2017-10661)

  - The acpi_ns_evaluate() function in     drivers/acpi/acpica/nseval.c in the Linux kernel     through 4.12.9 does not flush the operand cache and     causes a kernel stack dump, which allows local users to     obtain sensitive information from kernel memory and     bypass the KASLR protection mechanism (in the kernel     through 4.9) via a crafted ACPI table.(CVE-2017-13695)

  - The acpi_ps_complete_final_op() function in     drivers/acpi/acpica/psobject.c in the Linux kernel     through 4.12.9 does not flush the node and node_ext     caches and causes a kernel stack dump, which allows     local users to obtain sensitive information from kernel     memory and bypass the KASLR protection mechanism (in     the kernel through 4.9) via a crafted ACPI     table.(CVE-2017-13694)

  - The acpi_ds_create_operands() function in     drivers/acpi/acpica/dsutils.c in the Linux kernel     through 4.12.9 does not flush the operand cache and     causes a kernel stack dump, which allows local users to     obtain sensitive information from kernel memory and     bypass the KASLR protection mechanism (in the kernel     through 4.9) via a crafted ACPI table.(CVE-2017-13693)

  - The tcp_disconnect function in net/ipv4/tcp.c in the     Linux kernel before 4.12 allows local users to cause a     denial of service (__tcp_select_window divide-by-zero     error and system crash) by triggering a disconnect     within a certain tcp_recvmsg code path.(CVE-2017-14106)

  - The native Bluetooth stack in the Linux Kernel (BlueZ),     starting at the Linux kernel version 3.3-rc1 and up to     and including 4.13.1, are vulnerable to a stack     overflow vulnerability in the processing of L2CAP     configuration responses resulting in Remote code     execution in kernel space.(CVE-2017-1000251

  - )

  - The prepare_vmcs02 function in arch/x86/kvm/vmx.c in     the Linux kernel through 4.13.3 does not ensure that     the 'CR8-load exiting' and 'CR8-store exiting' L0     vmcs02 controls exist in cases where L1 omits the 'use     TPR shadow' vmcs12 control, which allows KVM L2 guest     OS users to obtain read and write access to the     hardware CR8 register.(CVE-2017-12154)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:3083 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.

    Security Fix(es):

    * A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4     and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment     reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a     denial of service on the system. (CVE-2018-5391)

    * kernel: out-of-bounds access in the show_timer function in kernel/time/posix-timers.c (CVE-2017-18344)

    * kernel: Integer overflow in udl_fb_mmap() can allow attackers to execute code in kernel space     (CVE-2018-8781)

    * kernel: MIDI driver race condition leads to a double-free (CVE-2018-10902)

    * kernel: Missing check in inode_init_owner() does not clear SGID bit on non-directories for non-members     (CVE-2018-13405)

    * kernel: AIO write triggers integer overflow in some protocols (CVE-2015-8830)

    * kernel: Use-after-free in snd_pcm_info function in ALSA subsystem potentially leads to privilege     escalation (CVE-2017-0861)

    * kernel: Handling of might_cancel queueing is not properly pretected against race (CVE-2017-10661)

    * kernel: Salsa20 encryption algorithm does not correctly handle zero-length inputs allowing local     attackers to cause denial of service (CVE-2017-17805)

    * kernel: Inifinite loop vulnerability in madvise_willneed() function allows local denial of service     (CVE-2017-18208)

    * kernel: fuse-backed file mmap-ed onto process cmdline arguments causes denial of service (CVE-2018-1120)

    * kernel: a null pointer dereference in dccp_write_xmit() leads to a system crash (CVE-2018-1130)

    * kernel: drivers/block/loop.c mishandles lo_release serialization allowing denial of service     (CVE-2018-5344)

    * kernel: Missing length check of payload in _sctp_make_chunk() function allows denial of service     (CVE-2018-5803)

    * kernel: buffer overflow in drivers/net/wireless/ath/wil6210/wmi.c:wmi_set_ie() may lead to memory     corruption (CVE-2018-5848)

    * kernel: NULL pointer dereference in ext4_xattr_inode_hash() causes crash with crafted ext4 image     (CVE-2018-1094)

    * kernel: vhost: Information disclosure in vhost/vhost.c:vhost_new_msg() (CVE-2018-1118)

    * kernel: Denial of service in resv_map_release function in mm/hugetlb.c (CVE-2018-7740)
